A set of novel pyridine-annulated analogs of purinones, adenines and their oxo/thio congeners, xanthines, guanines, and purine-2,4-diamines as potential anticancer agents was considered based on the scaffold-hopping and hybridization of known anticancer agents/drugs, purine derivatives and our recently developed imidazo-pyridine derivatives. Towards the synthesis of these compounds, a new approach
基于已知的抗癌药物的支架跳跃和杂交,考虑了一组新颖的吡啶修饰的嘌呤类,腺嘌呤及其氧代/硫代同源物,黄嘌呤,鸟嘌呤和嘌呤-2,4-二胺类化合物。药物,嘌呤衍生物和我们最近开发的咪唑并吡啶衍生物。为了合成这些化合物,一种新方法涉及方便地制备3-氨基-2-羧乙基取代的咪唑并[1,2- a研发了]-吡啶及其作为构建稠环的基础。该方法使得能够制备许多对于每个类别具有相关取代的化合物。发现一些吡啶修饰的腺嘌呤及其氧代/硫代类似物,黄嘌呤和嘌呤-2,4-二胺在肾癌细胞中具有显着的抗癌活性,并且对正常细胞的细胞毒性相对较小。它们比抗癌药依托泊苷和阿霉素相对更具活性。发现代表性的吡啶环化的腺嘌呤衍生物化合物(22)具有显着的细胞凋亡。
